摘　　要：沉降速率分析成果可用来判别工程的安全和填筑速率的合理性,工后沉降量的分析成果是决定卸载时间的主要依据。文中对双曲线预测模型及原理进行介绍,结合内蒙古沙漠地区乌嘎一级公路路基沉降变形的实例进行分析,得出软土路基沉降的动态变化情况。Settlement analysis consists of sedimentation rate and calculation analysis in post-construction settlement. The sedimentation rate can be used to determine the safety of the works and the rationality of the filling rate, and the post-construction settlement is the main basis of the decision to uninstall time. In this paper, based on the subgrade settlement of Wuga highway in the desert areas of Inner Mongolia, the hyperbolic prediction model and principles are introduced, and the dynamic changes of the soft soil subgrade settlement are achieved.

关 键 词：沉降速率 工后沉降量 双曲线预测 路基沉降
